Frostytech have fresh heatsink review for you today, it's the Apack Zerotherm BTF-92 Overclockers Edition. Take a look here, this CPU cooler is compared to about 50 other Intel and AMD heatsinks.
"Apack's BTF92 OC ed. heatsink features a
free-floating UFO-bearing 92mm fan spinning at 2300RPM by default. The included fan speed controller can bring impeller speeds down to 1000RPM if desired. A pair fo blue LEDs illuminate the translucent impeller blades. Made entirely of copper, save for a cast aluminum base cap, the BTF92 OC ed. heatsink weighs a hefty 638grams and has 3624 square centimeters of surface area.
The unit stands 130mm tall, and comes with mounting brackets for both Intel and AMD processors. Fan noise is moderate, with the speed controller in play near-silent."
